(cherry picked from commit d384a78fd1e2bb95a59bb251d08184e9456596e7)

gives about 2x performance improvement on sse enabled chips.

fix copying of oneshot sha1 context. also decrease the size
of "small buffer", to make context smaller (and context copy
faster in most cases); it should be still enough to catch
most hmac operations.

there was a bug sha context copying, that caused all hmac users
(and possibly others) to crash. also implemented a third
intermediate hashing mode with small buffer: it'll speed up
hashing in most cases considerably (packets / certificates to
be hashed are not usually too long).

added maintainer to several packages as well
